301 redirect
A 301 redirect is a permanent redirect which passes between 90-99% of link juice (ranking power) to the redirected page. 301 refers to the HTTP status code for this type of redirect. In most instances, the 301 redirect is the best method for implementing redirects on a website.

To explain the text that should be contained within your .htaccess file, I will start by using a very basic example such as renaming a page on your website.

For example, if you wanted to change a pages URL from:

example.com/old.html
to:
example.com/new.html

To ensure the old page redirects to the new page, you would need to add the following code to your .htaccess file:redirect 301 /old.html example.com/new.html
Here’s an explanation of what the code above means:“redirect 301” tells search engines (and browsers) that your page has been moved permanently.“/old.html” – provides the old location of the page“example.com/new.html” – is the new location of the page you’re telling the server to redirect visitors to. This part of the code requires the complete URL to work properly.

302 redirect
A 301 redirect means that the page has moved to a new location, permanently. A 302 redirect means that the move is temporary. Search engines need to figure out whether to keep the old page, or replace it with the one found at the new location.

404 Not Found
The HTTP 404 Not Found Error means that the webpage you were trying to reach could not be found on the server. It is a Client-side Error which means that either the page has been removed or moved and the URL was not changed accordingly, or that you typed in the URL incorrectly.

Important HTTP Status Codes for SEOs and search engines200 OK
The request has succeeded. This is considered correct for most scenarios.

301 Moved Permanently
The requested resource has been assigned a new permanent URI and any future references to this resource should use one of the returned URIs. The 301 redirect, as it is commonly called by SEOs, should be utilized any time one URL needs to be redirected to another.

302 Found
The server is currently responding to the request with a page from a different location, yet the requestor continues to use the original location for future requests. This approach is not recommended. It is not an effective way to instruct search engine bots that a page or site has moved. Using 302 will cause search engine crawlers to treat the redirect as temporary and not give it the link juice (ranking power) abilities of 301 redirects.

404 File Not Found
The server has not found anything matching the Request-URI. No indication is given of whether the condition is temporary or permanent. This should occur any time the server can’t find a matching page request. Often times webmasters will display a text 404 error but the response code is a 200. This tells search engine crawlers that the page has rendered correctly and many times the webpage will get erroneously indexed.

410 Gone
The requested resource is no longer available at the server and no forwarding address is known. This condition is expected to be considered permanent. Clients with link editing capabilities SHOULD delete references to the Request-URI after user approval. If the server does not know–or has no facility to determine–whether or not the condition is permanent, the status code 404 (Not Found) should be used instead of 410 (Gone). This response is cacheable unless indicated otherwise.

503 Service Unavailable
The server is currently unable to handle the request due to a temporary overloading or maintenance of the server. The 503 should be used whenever there is a temporary outage (for example, if the server has to come down for a short period for maintenance). This ensures that the engines know to come back soon because the page/site is only down for a short time.
